GLOBE FOR INVERTED BURNERS.

No. 898,881. Specification of Letters Patent. Patented. Sept. 15, 1908.

Application filed 0mm 12, 1907. Serial No. 397,118.

To all whom it may concern:

a and is, when attached-to the upper portion Be it known that I, THOMAS HANNA, of

2, Without openings or perforations other Columbus, in the county of Franklin and than the spaces between the Wires forming State of Ohio, have invented a certain new the mesh. This globe 3 may be composed of and useful Improvement in Globes for In- 'wire cloth with a mesh ranging from ten to verted urners, of which the following is a I one hundred wires to the square inch.

Although I have shown a wire globe 3 in the drawing of.certain shapes, I do not desire to limit myself thereto.

The advantages of my invention are that while the passage of air isv permitted to the burner, injurious drafts are prevented, and the escape of falling incandescent )ieces of the mantle is rendered impossible. The globe, when composed entirely of metal, is also much more durable than when composed wholly or in part of glass.

exact description, referencebeing had to the accompanying drawing, forming part of this specification, in'which Figure 1 is a side elevation illustrating my I improved globe, and Fig. 2 is a like View of a modification.

Heretofore in the use of inverted burners such as are employed with incandescent mantles, there has been m re or less danger of fire owing to the incandescent portions of the mantle dropping through the air aper. tures in the globe surrounding the burner. Having thus described m'yinven'tion, What Another objectionable feature is that these i I claim and desire to secure by Letters air passages cause objectionable drafts of air Patent is:

1. In an incandescent gas burner of the inverted type, a globe of fine Wire mesh constructed to protect the mantle from drafts of air and to difiusethe light.

2. An incandescent gas burner of the inverted type comprising aimantle inclosure of fine wire mesh constructed to form a light diffusing medium.

The object of my invention is to provide a globe which will permit of a free passage of air to the burner without possibility of the escape of incandescent portions of the mantle, and without such apertures as Would cause injurious drafts of air. To this end it consists in a globe, the lower portion of which is composed of wire mesh.

In the drawing, 2 represents the upper my hand. portion of the globe for incandescent burn- THOMAS HANNA ers, which may be formed of sheet metal, glass, or other suitable substance. Attached j Witnesses: to the upper portion 2 is a M. A. BARTH,
